Hi ChemTeacher,

Anything is possible. My pec flap is in the cervical neck is not a problem, but I had cancer come back at the surgery lines from prior neck dissections. I read, for some reason, if cancer comes back, it often comes back at the surgical lines, probably microscopic cancer, maybe seeding, I would think, and it also comes back just outside the surgical field, margins, maybe field of cancerzation, synchronous or microscopic cancer. Recurrence average is about 8 months, not that it is, but the best thing is to have it checked as soon as you can as a precaution, and hopefully is nothing. Like before, if anything unusual doesn't go away in two weeks, have it checked.

Good luck.
